Upwelling and the El Niño “Southern Oscillation” (ENSO) are recurrent climatic phenomena in the southeastern Pacific Ocean that severely affect the reproduction and growth of pelagic fish populations. However, there are not long-term growth data from demersal fish populations to test these interconections in a long-term analysis. For this reason, a first extensive growth chronology was reconstructed from the annual growth of sagittal otoliths as a proxy for somatic growth for the cardinalfish (Epigonus crassicaudus). Adult fish ranging from 35 to 40 cm in fork length and from 39 to 63 years in age were collected off Chilean waters. The master chronologies were estimated for the period from 1974 to 2014, using the regional curve standardization approach (RCS) and linear mixed models (LMMs). Growth indexes derived from both approaches followed a similar trend and were positively correlated with the Humboldt Current Index (HCI) and negatively with ENSO, Pacific Decadal Oscillation and sea surface temperature. LMMs showed that a 75% of growth variability was explained by the age of increment formation and HCI was the environmental index that most significantly affected the annual growth of cardinalfish followed by the sea surface temperature in spring. A reduced growth phase from 1974 to 1996 contrasted with a higher growth period from 1997, matching the 1997/1998 climatic regime shift, demonstrating that the enhanced growth for cardinalfish was associated with upwelling of nutrient rich water to the surface, triggering an increase of the primary and secondary productivity during the prevalence of a cold regime period in the Humboldt Current System. The consistence between RCS and LMM methods was indicative that both approaches are promising to evaluate the influence of environmental drivers on the growth condition of a demersal fish population in a highly productive marine ecosystem.

上升流和厄尔尼诺“南方涛动”（ENSO）是太平洋东南部反复出现的气候现象，严重影响中上层鱼类种群的繁殖和生长。然而，没有来自底层鱼类种群的长期增长数据来在长期分析中测试这些相互联系。出于这个原因，第一个广泛的生长年表是从矢状耳石的年生长中重建出来的，作为红雀（Epigonus crassicaudus ）体细胞生长的代表）。在智利水域收集了叉长 35 至 40 厘米、年龄 39 至 63 岁的成年鱼。使用区域曲线标准化方法 (RCS) 和线性混合模型 (LMM)，估计了 1974 年至 2014 年期间的主年表。两种方法得出的增长指数遵循类似的趋势，与洪堡海流指数 (HCI) 呈正相关，与 ENSO、太平洋年代际振荡和海面温度呈负相关。LMMs 表明，75% 的生长变异性可以用增量形成的年龄来解释，而 HCI 是对红雀鱼年生长影响最显着的环境指数，其次是春季海面温度。1974 年至 1996 年的增长阶段减少，而 1997 年的增长阶段则较高，与 1997/1998 年的气候变化相匹配，表明红雀鱼的生长加快与富含营养的水向上涌到地表有关，在洪堡海流系统寒冷时期盛行期间引发初级和次级生产力的增加. RCS 和 LMM 方法之间的一致性表明，这两种方法都有望评估环境驱动因素对高产海洋生态系统中底层鱼类种群生长条件的影响。
